The development of aquaculture in the Marine Protected Area (KKP) has to recognize the sustainability and the balancing of the ecosystem in that area. It causes limited rights of users who want to develop their business, where the issuance of permits and business management regulations is an obligation that must be followed by aquaculture business developers in the KKP area. The study aimed was to formulate the technical directions in developing the potential for aquaculture business in the Marine Protected Area of Datok Bandar (KKPD) at Lingga Regency. The method used in this research is a descriptive quantitative using analysis of the carrying capacity of the environment for aquaculture, water quality parameters, and a participatory approach. The results showed that the potential area to be developed for aquaculture was 3,736.01 ha. However, based on the carrying capacity analysis, only 268,420 ha or 7.2% from the existing potential can be utilized for aquaculture. Furthermore, based on the water quality measurements for aquaculture, the KKPD area was divided into 3 designations groups of aquaculture areas, namely the KJT, KJA, and seaweed. The number of aquaculture business units that were allowed in this area was 16,776 units consisting of 10,066 small business units and 6,710 medium business units with 7 types of superior fish. The limitation of land area and some business units in conservation areas were important to ensure the sustainability of the environment in the future. The implication of this research could be used as a basis for issuing aquaculture business permits, and to ensure that small-scale aquaculture fishermen have a large proportion. In addition to ensuring the existence of local communities who were generally small farmers, conservation areas were very vulnerable to environmental changes, so the risk factors and impacts of business utilization were important to consider.

Identification and estimation of seahorse population in the marine environment are difficult to obtain. Nowadays, the observations use visual techniques, biologic and statistics. Bio-statistics approach has some limitations, such as times consuming and low accuracy. An approach was required to provide more accurate information, comprehensive, and based on telemetry (underwater acoustic). Acoustic reflection is an important information to observe underwater objects that can be used for stock assessment and behavioral studies. This research is a preliminary observation and measurement of seahorse Target Strength (TS). The results show that there are differences in TS value of seahorse at the active and passive moving condition. The fluctuations of TS values in active conditions are higher than those in passive conditions. This study has also found that the average TS value of seahorse in active moving conditions is -54.49 dB (± 3 dB). It is greater than the mean TS value in passive moving conditions -59.64 dB (± 3 dB). The approach of immobile fish (the passive moving condition) on the seahorse is better to increase the correlation value between TS to size. The relationship between TS and the size of the seahorse are discussed in the results of this study

Pengelolaan pesisir yang sangat kompleks cenderung dibagi menurut batas administratif yang umumnya tidak memiliki relevansi ekologis. Jika domain perencanaan dilakukan secara terpisah maka konektivitas dan proses ekologi dua arah akan terganggu. Keterpaduan penataan ruang darat dan laut (zona pesisir) penting dilakukan terkait evaluasi program atau kebijakan baru yang berdimensi ruang. Peran informasi geospasial penting sebagai model spasial untuk mengintegrasikan rencana tata ruang darat dan laut serta melihat keselarasan atau harmonisasi dan sinkronisasi program perencanaan pembangunan baik di sektor darat maupun laut. Tulisan ini berfokus pada analisis tingkat keselarasan tahap integrasi yang sedang dilakukan pada kedua dokumen rencana tata ruang tersebut, guna melihat potensi tumpang tindih pemanfaatan ruang di kawasan pesisir Pulau Bintan dengan pendekatan overlay peta spasial. Hasil yang diperoleh menunjukkan secara umum perencanaan ruang darat dan laut memiliki tingkat keselarasan yang baik, namun masih terdapat potensi konflik pemanfaatan ruang di wilayah 4 (Bagian Timur Pulau Bintan) terkait kawan industri yang dialokasi pada bagian darat berdampingan dengan kawasan konservasi perairan pada perairan pesisir. Pada tulisan ini juga telah dijabarkan rekomendasi kebijakan untuk meminimalisisr konflik sosial dan dampak lingkungan di masa akan datang. Very complex coastal management tends to be divided according to administrative boundaries which generally have no ecological relevance. If the planning domains are carried out separately, connectivity and two-way ecological processes will be disrupted. The integration of land and sea spatial planning (coastal zones) is important in relation to the evaluation of new programs or policies with a spatial dimension. The role of geospatial information is important as a spatial model to integrate land and sea spatial plans and see the alignment or harmonization and synchronization of development planning programs in both the land and sea sectors. This paper focuses on the analysis of the level of alignment of the integration stage that is being carried out on the two spatial plan documents, to see the potential overlap of space utilization in the coastal area of Bintan Island with a spatial map overlay approach. The results obtained show that in general land and sea spatial planning has a good level of alignment, but there is still a potential for conflict over spatial use in area 4 (Eastern part of Bintan Island) related to industrial areas which are allocated on land side by side with marine conservation areas in coastal waters. This paper also describes policy recommendations to minimize future social conflicts and environmental impacts.
